„ Fragmentation: When the size of a unicast frame exceeds the fragmentation
threshold, it will be fragmented before the transmission. It should have a value of
256-2346 bytes, with a default of 2346. If you experience a high packet error rate,
you should slightly decrease the Fragmentation Threshold.
„ RTS Threshold: RTS/CTS frames are used to gain control of the medium for
transmission. Any unicast (data or control) frames larger than specified RTS threshold
must be transmitted following the RTS/CTS handshake exchange mechanism. The
RTS threshold should have a value between 256-2347 bytes, with a default of 2347. It
is recommended that this value does not deviate from the default too much.
„ Beacon Interval: The device broadcasts beacon frames regularly to announce its
existence. The beacon Interval specifies how often beacon frames are transmitted in
time unit of milliseconds. The default value is 100, and a valid value should be between
1 and 65,535.
„ AckTimeOut: When a packet is sent out from one wireless station to the other, it will
waits for an Acknowledgement frame from the remote station. The station will only
wait for a certain amount of time, this time is called the ACK timeout. In most
conditions, please put ACKtimeout value at zero(default value). The AP will calculate
the ACKtimeout automatically when the value is zero. However, you can also enter
the ACKtimeout manually.
„ Preamble Type: A preamble is a signal used in wireless environment to synchronize
the transmitting timing including Synchronization and Start frame delimiter. In a "noisy"
network environment, the Preamble Type should be set to Long Preamble. The Short
Preamble is intended for applications where minimum overhead and maximum
